1. What do I wrap ABS pipes that are being in slab that is about to be poured?

2. I'm a newbee, please send all advice on running copper lines under ground (from house to garage). I am concerned about heat loss (water heater is in the house). What do I use for this and to protect the pipe from being damaged? How deep do I barry them?

3. Is it better to have the male end of a water line stick out of the sheet rock so the flex lines can be screwed on easily (or should I leave it where it will be barried by sheet rock)? The flanges I'm about to use are almost flat so they will not cover much.
